XL5: Array Formula Doesn't Recalculate Using Calculate Method

• Microsoft Excel for Windows, version 5.0c
• Microsoft Excel for the Macintosh, versions 5.0, 5.0a

SYMPTOMS

In Microsoft Excel, when you use the Calculate method in a Visual Basic procedure to recalculate a range of cells, if the range contains an array formula, one of the following occurs:

• If the array formula is in a single cell, the formula is no longer an array after you run the procedure

      -or-
  

• If the array formula is in a range of cells, the range is not recalculated.

CAUSE

This problem occurs when you calculate any array formula using the Calculate method, whether the formula contains a custom function or a built-in function.

Note that this problem does not occur in Microsoft Excel for Windows version 5.0.

2. Click the Calculation tab.

3. Under Calculations, click Automatic, and then click OK.

Method 3

NOTE: If you use this method, and you later find errors on your sheet that are related to array formulas, close the sheet without saving your changes and use either method 1 or 2.
